English Wikipedia has an article on:

In a periodic scale, the equave (/ˈiːkwɪv/ EE-kwiv or /ˈiːkwəv/ EE-kwəv), also called interval of equivalence, equivalence interval, formal octave[1] or pseudo-octave[2][note 1], is the interval such that pitches separated by it are considered equivalent and are elements of the same pitch class.

The equave of a scale is generally the same as its period or a multiple of its period.

Etymology

The term equave was coined by Inthar. It is a portmanteau of equivalence and octave.

Notes

  1. The term pseudo-octave generally designates any kind of equave, although it is sometimes used specifically to designate a stretched or compressed octave.
